Microanalysis of blue pigments from the Ptolemaic temple of Hathor (Thebes), Upper Egypt: a case study

A microanalysis of blue pigments from the Ptolemaic temple of Hathor in Ancient Thebes reveals that Egyptian blue (cuprorivaite) was used, with significant lead content in its glass phase, indicating the use of leaded bronze scrap in production. Optical and advanced microscopy techniques identified gypsum and dolomite as the underlying paint layers. Some pigments exhibited discoloration, turning green or black. This study enhances our understanding of painting materials from the Ptolemaic era, providing insights into ancient Egyptian artistic practices.
